How to add AND and OR in SDP filter criterion

Content (required):

We have a scenario, in which we need to set AND and OR in Filter Criterion for SDP. For example, we need to set below:

((invoiceNumber LIKE '%abc%') and (policyGroup LIKE '%Employee Benefit%') and (approvalStatus != 'Not Required' or postingStatus != 'Posted'))

I tried it by using javascript function below.

PageModule.prototype.prepareSearchQueryParams = function (q1, q2, q3, q4) {

    var req = [];

    if (q1.value) {       req.push(q1);     }

    if (q2.value) {      req.push(q2);    }

    if (q3.value) {      req.push(q3);    }

    if (q4.value) {      req.push(q4);    }

    return req;
